Westonbirt Arboretum's creator, Robert Stayner Holford, was an ambitious man.
He not only created the arboretum, but also rebuilt Westonbirt House (now Westonbirt School) and added formal pleasure gardens.
Robert Holford, in keeping with wealthy estate owners of his day, created the arboretum for pleasure and as testament to his taste and wealth.
Plant hunting heritage
The Victorian era was a time of great excitement in the plant world, with plant-hunters like David Douglas bringing new and exotic species from the farthest reaches of the British Empire.
Holford financed plant collecting expeditions and the arboretum still contains many of the original plants brought back from these trips.
By 1855, much of the Old Arboretum had been laid out, including Main Drive, Specimen Avenue and the three main rides - Holford Ride, Morley Ride and Jackson Avenue. Influenced by the Picturesque movement, the emphasis at Westonbirt was always on aesthetics, rather than science.
Expanding the collection
From the 1880s, the dominant figure in the arboretum's development was Robert Holford's son, Sir George.
He expanded the arboretum across the valley into Silk Wood, planting new species amongst the woodland that had occupied the site for centuries and creating vast drives with wide verges and bays of ornamental trees.
Sir George was also responsible for planting many of the rhododendrons and maples for which Westonbirt Arboretum is so famous today.
Sir George left no heir when he died in 1926 and the estate passed to his nephew, the Fourth Earl of Morley. In 1927 the mansion was sold and became a girls' school and the estate was split up. The Fourth Earl died in 1951 and Westonbirt Arboretum passed to his brother for a brief period.
The Forestry Commission
In 1956 the entire 600 acres (240 hectares) were handed over to the Forestry Commission, who had the huge task of making it safe for the public to enjoy its beauty for the first time.
Like Holford the Forestry Commission had ambitious plans - including mapping, cataloguing and labelling the collection for the first time, as well as replanting and creating new areas, like The Link, in Silk Wood.
From its beginnings as a rich man's passion, the arboretum now revolves around the unique collection of trees and shrubs. It has become a vital resource for conservation, recreation and education, with over 350,000 visits a year to connect with the tree collection and enjoy its beauty and tranquillity.
